Apparatus and safety mechanism for use with
mechanically fireable flash devices

ABSTRACT

PHOTOGRAPHIC APPARATUS AND A SAFETY MECHANISM FOR PREVENTING THE ACCIDENTAL FIRING OF A MECHANICALLY FIREABLE FLASH DEVICE WHEN THE DEVICE IS FIRST POSITIONED ON THE APPARATUS. THE FLASH DEVICE INCLUDES A STRIKER LODGED IN AN ENERGIZED POSITION FROM WHICH IT IS RELEASABLE BY THE APPARATUS TO FIRE THE DEVICE. THE APPARATUS HAS A SENSING AND/OR ACTUATING MEMBER MOVABLE INTO NON-RELEASING EN-   GAGEMENT WITH THE STRIKER IN RESPONSE TO POSITIONING OF THE DEVICE ON THE APPARATUS, AND FURTHER INCLUDES MECHANISMS FOR PREVENTING THE ACCIDENTAL RELEASE OF THE STRIKER DURING SUCH MOVEMENT OF THE MEMBER INTO ENGAGEMENT WITH THE STRIKER.
